Updated our Razr M's to the new Android version. My wife's works ok, but on mine, text messaging crashes when opened. I can sort of use "hangouts", but it's clumsy, and I don't always get audible notifications on an incoming text. And I'll be sending something direct to customer service as well.
wd8chl We want you to have a fully functioning device. Our apologies that you have had so many issues since the update on the Razr M. Have you tried to forceslose the messaging app and other apps that are crashing? Go to settings, apps,all and select each one and clear app data, force close and restart the phone.
